UNITED STATES FRANK A. KING, OF ENGLEWOOD, COLORADO.

SPOTLIGHT.

Application filed March 18, 1922.

T all whom it may concern:

Be it known that I, FRANK A. KING, a citizen of the United States, residing at Englewood, in the county of Arapahoe and State of Colorado, have invented certain new and useful Improvements in Spotlights; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to new and useful improvements in lights, and more particularly to what is known as spot lights for motor vehicles, the main object of the invention being the provision of mounting and operating means whereby the light may be mounted on a wind shield or the like in such manner that the light itself will be forward of the wind shield, with an operating handle behind the wind shield, means being provided whereby the light may be turned to any direction desired by movement of the handle.

A further object of the invention is the provision of a spot light mounted on a ball and socket joint carried by a stationary support having means within the support and joint for turning the light upon said joint to the direction desired.

A further object of this invention is the provision of a spot light having a new and improved means including a ball and socket joint with operating means partly within said joint for manipulating the light whereby the same may be elevated and depressed or moved from side to side, or the said two movements may be combined and resolved, at the will of the operator by the use of a single operating handle.

With the above and other objects in view, the invention consists in the novel features of construction, combination and arrangement of parts hereinafter more fully set forth, pointed out in the claims and shown in the accompanying drawings, in which:

Figure 1 is a top plan view of a light constructed in accordance with my invention;

In the construction of my improved spot light, I provide a supporting housing or sleeve 1 having a bearing sleeve 2 formed integral with one end of the supporting sleeve and further provided with an annular flange 8. In mounting the supporting element upon the windshield 4 the windshield is first provided with an opening adapted to receive the bearing 2 and the flange 3 is fitted tightly against one face of the windshield 1. In order to prevent movement on the part of the bearing 2, a plate 5 is mounted upon the side of the windshield opposite the flange 3 and this plate 5 is retained in position by means of a stop nut 6 which is threaded upon the outer end of the bearing sleeve 2 and bears against the plate 5. From this it will be apparent that when the stop nut 6 is screwed tightly onto the bearing sleeve 2, the supporting sleeve 1 will be securelv positioned with respect to the windshield l.

Mounted for rotation within the sleeve 1 is an operating shaft 7 having secured to its outer end a handle member 8. The portion of the shaft 7 within and adjacent the be is reduced as eieerly re "oh'ably mounled nesei i ihed. S} is provided days which rorresponding key w vs in sieeve 1 to 7' ion with sh iii;

Mounted within the bail and disposed above the shaft 7 end arran ed -nt angles thereto is a second pinion said pinion 35 being mounted parallel with the pinion. 32 end having longitudinal rihs adapted to mesh with the ribs on the pinion 32 wherehy upon rotation of the pinion 32 through the medium of the shaft hrough manual power being appiied to the She r tetion oi" the shaft 7 at the 7 rotary movement is imparted to the pin ion 35. The outer end of the pinion is extended into the slot 36 formed in an arcu ate rack member 37 said rack member being carried by the socket 38 which partially encloses the ball 10. Attention is called to the fact that one side of the slot 36 is provided with rack teeth 39 adapted to mesh with the ribs on the pinion 35 whereby upon rotation of the pinion an oscillating movement is imparted to the socket lilounted within a bearing t0 and emb1.a="-- ing the pinion 35 is a bevel gear 41 which is arranged whereby to engage with the bevel gear 29 whereby upon rotation of the shaft 7 movement is imparted thereto through the medium of the bevel gear 29. The bevel gear ll is provided with spaced lugs -12 fitting into the slot 36 of the rank 3'? whereby rotating movement of the gear ll will impart an oscillating movement to the socket 38 at right angles to the movement imparted through the pinion 35. Mounted upon this socket 38 and secured thereto is the lamp 28 and from the above description taken in connection with the accompanying drawings, it will be readily apparent that when the handle 8 is moved toward or away from the windshield by the operator a reciprocating movement will be imparted to the shaft 7', thus imparting a rotary movement to the pinions 32 and 35 and through the engagement of the pinion 35 with the rack 37 which is carried by the socket 38 movement will be imparted to the lamp 28 in a vertical plane whereby said lamp may be readily elevated or depressed at the will of the operator. If it is desired to move the lamp in a horizontal plane or from side to side, the handle 8 is rotated either to the right or left of the operator and through this movement the shaft 7 is rotated, thus imparting a rotating movement to the gears 29 ane'l ll and by having the lugs e2 disposed within the slot 36 a substantially horizontal. movement is imparted to the socket 38 which in turn imparts a similar movement to the lamp in a horizontal plane.

The socket member 38 as illustrated in the accompanying drawings, is preferably made in two sections, each section being provided with an arcuate flange portion bolted or otherwise connected as shown at d3 whereby the several gears and pinions may be ged'in their proper relative positions in the bearings provided therefor in the ball 10 and the socket 38 then arranged over the ball with the end of the pinion 35 extending into the slot, 36 in the rack 37. This rack 37 may be attached to the socket 38 in any suitable manner and it is understood that the section of the socket to which the rack is applied is provided with an arcuate slot co-mating with the slot 36 in the rack, as illustrated in Figs. 10 and 12. Varirotary movement of the shaft will move the through said point in a plane sub-- stantially at right angles to the first mentioned point, and it will be obvious that with such a construction. a combination and resolution of the said two movements may be made which will result in moving the lamp in direct line or in any other line of movement desired from any point within the limits of its motion to any other point within those limits. lVhile the description is generally limi ed to movement in two planes at right angles to each other it will be understood that these two movements being made possible the light may be made to move in any desired manner or on any desired line from one point to another and that its move ment is by no means limited to two right angle planes.

I claim:

1. An adjustable light support including an operating shaft, a lamp, a ball and socket connection between the shaft and lamp, a sleeve mounted upon the shaft, a rotatable pinion carried by the ball, a rack carried by the socket, means forming connection between the shaft and sleeve whereby longitudinal movement of the shaft will impartrotary movement to the sleeve and additional means connecting the sleeve with the pinion whereby to rotate said pinion, imparting movement to the socket whereby to move the lamp, from any given point, in one plane and additional means forming connection between the socket and shaft whereby upon rotation of the shaft the lamp will be moved, from said point, in a plane at substantial right angles to said first mentioned plane.

2. An adjustable light support including an operating shaft, a lamp, a ball and socket connection between the shaft and lamp, a sleeve mounted upon the shaft and keyed for rotation therewith, a gear at one end of said sleeve, a second gear co-mating therewith, means forming connection between the second gear and the socket whereby upon rotation of the shaft the lamp will be caused to move, from any given point, in one plane and additional means forming connection between the shaft and the socket whereby upon longitudinal movement of the shaft the lamp will be moved, from said point,

in a plane at substantial right angles to the first mentioned plane.

3. An adjustable light support including an'operating shaft, a lamp, a ball and socket connection between the shaft and lamp, a sleeve mounted upon the end of the shaft projecting into the ball, means forming connection between the shaft and sleeve whereby to rotate said sleeve upon longitudinal movement of the shaft, a pinion at right angles to the sleeve, a gear on the pinion a second gear carried by thesleeve co-mat ing with the gear on the pinion, an arcuate gear mounted within the ball for rotation upon the pinion, a groove within said arcuate gear, a rack having connection with the socket and extending into said groove and co-mating with the pinion whereby upon longitudinal movement of the shaft the lamp will be moved, from any given point, in one plane and means forming connection with the shaft and the arcuate gear whereby upon rotating movement of the shaft the lamp will be moved, from said point,

4-. A device of the class described includ ing operating shaft, a ball and socket joint supported at one end thereof, a lamp mounted upon the joint for movement with the socket portion, a rack member carried by the socket portion of the joint, a bevel gear arranged within the joint and mounted upon the shaft for rotation therewith, a second bevel disposed at right angles to the first gear and meshing therewith, means forming connection between the rack and the second gear whereby rotation of said gears through rotary movement of the shaft will move said lan'ip, from any given point, in one plane and additional means forming connection between the shaft and the rack whereby longitudinal movement of the shaft will impart movement to the lamp, from said point, in a plane at substantial right angles to said first mentioned plane.
